摘要
简述了110kV变电站噪声源特性。以邻港变电站作为噪声预测研究对象,利用Cadna/A软件分别对5种主流的110kV户外变电站噪声预测模型进行仿真预测。通过预测值与实测值的对比分析表明:110kV户外变电站采用水平+垂直面声源模型能较好地反映变电站噪声衰减情况,并对声源尺寸及源强选取、噪声控制方案提出了建议。
In this paper,the noise source characteristics of 110 kV substation are briefly described.Taking the Lingang substation as the research object,the noise prediction models of 110 kV outdoor substation are simulated and predicted by using Cadna/A software.The comparison between the predicted and measured values shows that the noise attenuation of 110 kV outdoor substation can be well reflected by using the horizontal+vertical plane sound source model.Suggestions are also put forwardon the size and intensity of the sound source and the noise control scheme.
